1.2 Brief description
The Mixerpac 2564 is delivered as a complete, bidirectional and ready-to-install seal
ing cartridge. It seals the product chamber of a mixer vessel from the atmosphere.
It comprises a multiple mechanical seal (MS) with axially arranged seal ring pairs,
on the product side as well as on the atmospheric side an unbalanced seal, a shaft
sleeve, housings with an integrated self-aligning roller bearing and optional with an
installed cooling flange. The bearing is a floating bearing for the mixer shaft and
undertakes radial guiding tasks only.
1.3 The spring force and the hydraulic barrier pressure push the seal rings against the
mating rings. The seal faces are sealed from the shaft sleeve, respectively from the
housing, by sealing elements (e. g. O-rings). The faces of the seal ring and the mating ring are designed as sealing faces.
On the product side, the MIXERPAC has a mechanical seal with self-sealing effect

Mixerpac 2564 - Installation and Maintenance Instruction for Machinery Parts
in both directions, i. e. it seals both from the product side and from the barrier fluid
side. In the event of loss or of variations the product-side mechanical seal remains
closed (safety case).
Up to a pressure difference of Δp = 6 bar the MIXERPAC can be run with an unpressurized quench fluid (no danger of dry friction when the lubricating film ruptures).
1.4
Integrated bearing
!
The integrated bearing is a floating bearing for the mixer shaft and undertakes
radial guiding tasks only.
!
The installed bearing was designed for the loads (e. g. generated by speed,
speed changes, changes in load, thermal expansion of the shaft or housings)
when the MIXERPAC is run in accordance with these instructions. The application limits under item 1.1 must be observed to prevent damage to the bearing.
!
The installation chamber for the MIXERPAC must be checked against the corresponding drawing and table of dimensions so that the bearing is subjected only
to the loads generated by operations in accordance with these instructions. It
must be ensured that all dimensions, surface qualities and tolerances (e. g. concentricity, runout, fits) are observed. The specifications under e. g. ISO 21049
or API 682, DIN 28161, FLOWSERVE publications FSD101 respectively FSD127
must be observed.
!
Observe the maintenance intervals and relubrication times for the bearing under
the items 10.2 respectively 10.3, so that the installed bearing is supplied with
the optimum quantity of lubricant.
!
The installed bearing must be replaced once unacceptable wearing has been
established during the maintenance intervals for the whole machine, yet no later
than five years after the last installation / replacement.
!
Packing rings must be used to prevent fluids and solids from penetrating the
installed bearing.
1.5
Function
The barrier medium introduced in the barrier chamber must exhibit a pressure of 1-2
bar higher than the product in the mixer vessel.
!
The product pressure may not exceed the values given under item 1.1.
!
Up to a pressure difference of Δp = 6 bar the MIXERPAC can be run with an
unpressurized quench fluid (no danger of dry friction when the lubricating film
ruptures).
This causes the barrier fluid to form a seal film in the seal gaps, preventing product
from escaping into the atmosphere.
4
The fluid must always be present at the seal gaps, so that a seal film can be
generated. The seal film exists when the shaft is stationary.
The seal faces of the seal rings and the mating rings are separated from each other
by the film during shaft rotation and function without contact and wearing under
these conditions.
The choice of the barrier or the quench fluid depends on the respective use and must
be matched to the affected systems. In all cases a clean barrier or quench fluid must
be used.
The consumption of the barrier or the quench fluid depends on the respective operating data. The consumed quantity of barrier or quench fluid enters the product through
the product-side seal gap and the atmosphere through the atmospheric-side seal gap,
where it is drawn off through connection C.
!
The product pressure may not exceed the values given under item 1.1.
1.6
Function conditions
The MIXERPAC’s function is obtained only when the following conditions are fulfilled:
•
Filtered barrier or quench fluid (filter mesh < 5 µm) supplied at connection A.
•
Plane-lapped seal faces.
•
Perpendicularity between the seal faces and the shaft centerline.
•
Unforced clearance of the rotating parts within the specified tolerances.
•
Prevention of sedimentation on the surfaces of the shaft or shaft sleeve by e. g.
crystalliation or polymerisation.
•
Prevention of the product from adhering in the area at the seal gaps.
•
Permanent fluid film in the seal gaps.
•
Adherence to the specified operating data as per item 1.1 respectively the data
sheet.
If these function conditions are not fulfilled, the consumption of barrier or quench
fluid is increased and parts of the product can escape into the atmosphere.
Additionally, disregarding of these issues can result in high component temperatures.

tion, however, must be observed to prevent malfunctions that in
turn could directly or indirectly give rise to serious injury and / or
property damage.
2.2
The customer and / or the operator must ensure that all persons assigned to handle,
assemble or operate the machine have carefully read these installation and maintenance
instructions, before they commence any installation and maintenance work at the
MIXERPAC or before operate the machine. These personnel must be fully acquainted
with the layout and function of the MIXERPAC and the respective support system.
2.3 Damage may cause leakage in liquid or gaseous form. The hazardous effects correspond to those of the product, and there may be hazard to persons or the environment. The operator’s regulations concerning work safety, accident prevention,
and pollution for this plant section must be adhered to without exception.
2.4
!
Components coming into contact with the leakage must be corrosion-resistant or
corrosion-proof.
2.5 If the application of the MIXERPAC requirements is subject to the ATEX 94/9/EC,
then it is also imperative to comply with the annex for the assembly and maintenance instructions of the ATEX 94/9/EC guidelines.
2.6
!
MIXERPACs must be decontaminated before they are sent to FLOWSERVE for
maintenance or repair.
2.7
!
When employing elastomers of EP (ethylene-propylene) or butyl rubber, do not
use any grease or oil on a mineral basis as a barrier or quench fluid.
2.8 A loss, a re-establishment or a change of the power supply for the machine and
/ or the barrier system may not impair the properties of the MIXERPAC and / or
involves a risk of personal injury and / or considerable damage to property.
2.9 Assigned protection devices from the machine manufacturer must be accordingly
arranged and may no cause additional endangerments. They must ensure the
necessary range for the accessibility to maintenance work to the MIXERPAC.
2.10 The electrical supply of the machine must correspond to the protection targets
of the Directive 2006/95/EC.
No endangerments for persons and environment may proceed from a non electric power supply.
